Definitions

  • the invention relates to a chip card having a semiconductor chip that contains at least one memory, contacts and a device for contactless data transmission for supplying energy to the chip and for bi-directional data transmission from and to the chip, and a triggerable switch device disposed on the chip for connecting the memory either to the contacts or to the device for contactless data transmission, depending on a state of an output signal of a logic circuit connected to at least a voltage supply contact.
  • the logic circuit is constructed as a comparator having one input which is connected to the supply voltage contact.
  • the other input of the comparator is connected, through a rectifier and smoothing network, to coils for contactless energy and data transmission.
  • An output of the comparator operates as a function of voltages applied to its two inputs to trigger a multiplexer which operates as a function of the status of the output signal of the comparator to switch either the supply voltage and the signals of the contacts, or the supply voltage and the signals that have been derived from the signal received by the coils, to a microprocessor that is also connected to the multiplexer and has an associated memory.
  • a chip card comprising a semiconductor chip containing at least one memory; contacts and a device for contactless data transmission for supplying energy to the chip and for bi-directional data transmission from and to the chip, the contacts including a supply voltage contact; a logic circuit being connected to at least the voltage supply contact, the logic circuit supplying an output signal; and a triggerable switch device disposed on the chip and connected to the logic circuit for either connecting the memory to the contacts or to the device for contactless data transmission as a function of a state of the output signal of the logic circuit; the switch device assuming a position of repose when not triggered for connecting the memory to the device for contactless data transmission, and the switch device connecting the contacts to the memory only upon application of a voltage to the supply voltage contact, triggered by the logic circuit.
  • the logic circuit in order to further increase the security against misuse, is also connected to a clock signal contact.
  • the logic circuit is constructed in such a way that it triggers the switch device only when both a supply voltage and a clock signal are present.
  • the logic circuit is constructed with a microprocessor. As a result, additional safety functions can be introduced.
  • a data signal is also transmitted to the microprocessor, so that the microprocessor switches over the switch from the position of repose only whenever these three conditions are all met at once.
  • the data signal may be a command that tells the microprocessor to switch over the switch.
  • PIN personal identification number
  • a switchover of the switch is possible only when a positive comparison has taken place.
  • other authentication possibilities are conceivable as well, as a result of the use of the microprocessor.
  • the memory can be connected to the contacts only through the microprocessor. Especially high security is gained in this way.
  • the memory can be connected to the supply voltage contact only through a switch triggerable by the logic circuit. A further increase in security is accomplished in this way.
  • FIGURE of the drawing is a block circuit diagram of an exemplary embodiment of the invention.
  • FIG. 1 a basic circuit in which a memory 1 is connected to a coil 2.
  • a high-frequency signal that is received is supplied from the coil 2 over a first line 6 to a processing circuit 7, which extracts the clock and the data from it and supplies them through a switch device 9 to the memory 1.
  • the switch device 9 assumes a position of repose, in which a switch 91 of the switch device 9 connects the memory 1 constantly through the processing circuit 7 to the coil 2.
  • a control portion 92 of the switch device 9 may be triggered by a logic circuit 8, which is advantageously constructed as a microprocessor, so that the switch 91 connects the memory 1 through the microprocessor 8 to contacts 20.
  • a logic circuit 8 which is advantageously constructed as a microprocessor, so that the switch 91 connects the memory 1 through the microprocessor 8 to contacts 20.
  • this switchover can only occur when a supply voltage VDD is applied to a supply voltage contact 21 of the contacts 20 and supplies the microprocessor 8.
  • the switch device 9 can be triggered only by the microprocessor 8, so that it is not possible to use signals at the coil 2 to return the switch 91 to its position of repose and reconnect the memory 1 to the coil 2. Doing that is possible only once there is no longer any supply voltage VDD applied to the microprocessor 8.
  • the microprocessor 8 may be constructed in such a way that triggering of the switch device 9 is effected only when not only the supply voltage VDD but also a clock signal are applied to a clock signal contact 23.
  • the microprocessor 8 does not output a control signal to the switch device unless a data signal has previously been transmitted through a data contact 22.
  • a switch 10 which is also provided does not apply the supply voltage VDD, that is present at the supply voltage contact 21, to the memory 1 until it has been triggered by a corresponding signal from the microprocessor 8.
  • this control signal may be identical to the control signal for the control portion 92 of the switch device 9.
  • the control device 4 is intended to prevent the supply voltage for the memory 1 and the processing circuit 7 from becoming too high, as can happen if the card comes too close to a transmitter coil.
  • a voltage limiter in this control circuit has a certain deviation range, for example from 4.5 to 5.5 V. If a certain voltage limiter is at 4.5 V and the card is used in a contact reader device, it can happen that a supply voltage which is higher than the 4.5 V is impressed through the supply voltage contact 21, thus thermally threatening the voltage controller.
  • the voltage limiter can be switched over or turned off with the control signal.
  • the switch 10 does serve on one hand to connect the memory 1 to the supply voltage VDD only after a control signal is received from the microprocessor 8, but it also assures that the supply voltage, which in the contactless mode is applied through the line 5 from the coil 2 to the memory 1 and the processing circuit 7, will not reach the microprocessor 8.
  • This has the advantage on one hand of preventing the microprocessor 8 from being operated through the coil 2, but it also has the further advantage of assuring lower energy consumption in the contactless mode. Nevertheless, it may certainly be desirable not to require any switch in the supply voltage line on the integrated semiconductor chip, because such a switch always results in a voltage drop and therefore a limitation in the supply voltage range.
